This file photo taken on July 18, 2016 shows Turkish cleric and opponent to the Erdogan regime Fethullah Gulen sitting at his residence in Saylorsburg, Pennsylvania. Turkey has asked the German authorities to formally investigate reported sightings in Germany of a top suspect in last year's failed coup who still remains at large. Ankara blames the doomed bid on July 15, 2016, to oust President Recep Tayyip Erdogan on the US-based Islamic preacher Fethullah Gulen, and has implemented a ruthless crackdown on his suspected supporters. / AFP PHOTO / Thomas URBAIN
